areas as if they were prefixed with the symbol denoting the
area clicked on - `mode-line', etcetera.
When we throw away an unbound `down-' event, reset mock_input as
well.
* keyboard.c (Qevent_symbol_element_mask, Qmodifier_cache): Two
new symbols, used to implement caches on event heads. These take
the place of some of the caching that modify_event_symbol used to do.
(parse_modifiers_uncached, apply_modifiers_uncached,
lispy_modifier_list, parse_modifiers, apply_modifiers): New
functions, which replace format_modifiers and reorder_modifiers;
they can be useful elsewhere too.
(reorder_modifiers, modify_event_symbol): Re-implement these in
terms of parse_modifiers and apply_modifiers. modify_event_symbol
now uses a much simpler cache, and takes advantage of the caches
maintained by parse_ and apply_modifiers.
(follow_key): Don't modify NEXT if KEY has no bindings.
(read_key_sequence): Drop unbound `down-' events, and turn unbound
`drag-' events into clicks if that would make them bound. This
benefits from the rewriting of the modifier key handling code.
(syms_of_keyboard): Initialize and intern
Qevent_symbol_element_mask and Qmodifier_cache.
* keyboard.c (echo_prompt): Terminate the echo buffer properly
even when the string is too long to display in the minibuffer.
(echo_truncate): Just return echoptr - echobuf, rather than
calling strlen on echobuf.
* keyboard.c (modifier_names): The modifier is named "control",
not "ctrl".
instead of just saying it's 7; that way, we won't get screwed if
we add members to struct save_window_data.
* window.c (Fset_window_configuration): The pointer to the
saved window data is called `data', not just `d'.
frame, too.
(Fset_window_configuration): Restore the frame's selected window
using Fselect_window, and then restore the selected frame using
Fselect_frame.
(Fcurrent_window_configuration): Record the currently selected
frame. Update docstring to describe the information now recorded.
* window.c (Fset_window_configuration): Clean up the way we save
and restore the frame's size.
* window.c (struct save_window_data): Add a member called
focus_frame, to save and restore the screen's focus frame.
(Fset_window_configuration): Redirect the frame's focus as
indicated in the window configuration.
(Fcurrent_window_configuration): Record the frame's current focus.
modifiers containing a Meta_ keysym, use the Alt keysyms to
denote meta.
(construct_mouse_click): Set the down_modifier bit on mouse
button press events.
(XTread_socket): When processing keypress events, use
x_meta_mod_mask when processing ordinary ASCII characters, not
just when processing function keys and other non-ASCII events.
(XTread_socket): If we receive a MappingNotify event with the
`request' member set to `MappingModifier', then call
x_find_modifier_meanings to refresh x_meta_mod_mask.
event header gets the proper properties set on it, by recursing
and letting the same code build the properties for all event symbols.
* keyboard.c (Qmouse_click): Fix typo which assigned `mouse-click'
symbol to Qmouse_movement.
frame's focus, and have read_minibuf_unwind restore it; saving and
restoring the window configurations will take care of that.
(read_minibuf_unwind): Don't worry about restoring the frame's focus.
are not 5 elements long.
(EVENT_HEAD): Work correctly on all sorts of events, not just
events with parameters.
(EVENT_WINDOW, EVENT_BUFFER_POSN, EVENT_SCROLLBAR_BUTTON,
EVENT_WINDOW_POSN, EVENT_TIMESTAMP): These aren't useful
anymore; this information may appear twice in an event. These
are replaced by the POSN_ accessors, which are meant to be
composed with the EVENT_START and EVENT_END accessors.
(EVENT_START, EVENT_END): Two new accessors, to get at the
starting and ending position of an event.
(POSN_WINDOW, POSN_BUFFER_POSN, PONS_SCROLLBAR_BUTTON,
POSN_WINDOW_POSN, POSN_TIMESTAMP): New macros, to futher
diasassemble the values returned by EVENT_START and EVENT_END.
* keyboard.h (Qevent_unmodified): Extern declaration replaced by...
(Qevent_symbol_elements): This.
(EVENT_HEAD_UNMODIFIED): Use the Qevent_symbol_elements
property, rather than the Qevent_unmodified property.
testing for EVENT_HAS_PARAMETERS; EVENT_HEAD works properly on
all sorts of events now.
(read_key_sequence): Use the new accessors to decide in which window
an event occurred.
* keyboard.c (Qevent_unmodified): Replaced by...
(Qevent_symbol_elements): New property.
(syms_of_keyboard): initialize and staticpro the latter, not the
former.
* keyboard.c (readable_events): This doesn't need to scan and
discard mouse release events anymore; it just uses
EVENT_QUEUES_EMPTY.
(kbd_buffer_get_event): No need to skip past mouse release events.
* keyboard.c (button_down_location): New variable, which
stores the location at which each button was pressed, so we
can build a complete drag event when the button is released.
(make_lispy_event): When a button is pressed, record its
location in button_down_location, and turn it into a `down'
event. When a button is released, compare its release
location with its press location, and decide whether to call
it a `click' or `drag' event.
Change mouse movement events to be arranged like click events.
(format_modifiers): Note that the click modifier has no
written representation.
(modifier_names, modifer_symbols): New variables, used to
create the Qevent_symbol_elements property.
(modify_event_symbol): Change the format of the modified
symbol cache; there are too many modifier bits now to use a
vector indexed by a modifier mask. Use an assoc-list instead.
Document the format of the cache.
Put the Qevent_symbol_elements property on each new symbol,
instead of a Qevent_unmodified property.
(symbols_of_keyboard): Put Qevent_symbol_elements properties on
the symbols specified in head_table, not Qevent_unmodifed properties.
Initialize and staticpro modifier_symbols, and staticpro the
window elements of button_down_location.
(init_intervals, make_interval,
mark_interval, mark_interval_tree): New functions conditionally
defined.
(make_uninit_string): Call INITIALIZE_INTERVAL.
(INIT_INTERVALS, UNMARK_BALANCE_INTERVALS, MARK_INTERVAL_TREE):
New macros, conditionally defined.
(mark_object): Call MARK_INTERVAL_TREE in case Lisp_String.
(gc_sweep): If text properties are in use, place all unmarked
intervals on the free list. Call UNMARK_BALANCE_INTERVALS on
`buffer->intervals' when unmarking `buffer'.
(compact_strings): Include INTERVAL_PTR_SIZE in calculation for
target of bcopy when relocating strings.
(init_alloc_once): Call INIT_INTERVALS.
(make_pure_string): Include INTERVAL_PTR_SIZE in calculation of
`size'.
looking-at call doesn't clobber its value when we want to use it to back up
before the error we discard.
Make sure compilation-error-list is at least two elts long before checking
its first two elts for being in the same file.
and TEMP_SET_PT are function calls.
Similarly for BUF_SET_PT and BUF_TEMP_SET_PT.
Added DECLARE_INTERVALS to buffer structure to conditionally
compile an interval tree into it..
